Thanks, everyone. It's interesting (to me at least) how I got to this being completed. When I was at the location, I got rather excited about this particular scene/spot making a good photograph, and was thinking of something very similar to the feel of this although in color (the green vines as a contrast to the stone/brick work).
When I got back and started sorting through the images in LR, I briefly played with the shots of this but passed over them, disappointed that the images didn't seem to capture the feel when I was there. I kept going back to them because I couldn't shake the initial feeling that there was a photograph in there somewhere. I finally decided to try B&W and the image suddenly "clicked" with me and I got to this is fairly short order.
It was unusual for me in that I normally take an exposure visualizing a color or B&W final print, but this one almost escaped. It's funny how this went from almost landing on the cutting room floor (so to speak) to potentially being exhibited in our dining room on a blank spot of a large wall that I have been waffling about what photographs to hang there.
I guess it is vindication of my reluctance to delete images from the LR library that "don't work" as opposed to the ones I nuke that are defective (OOF, exposure errors, etc).
